MAX20012BATJJ/V+

MAX20012B is an automotive low-voltage 2-channel step-down controller. It is a dual-output, high-efficiency synchronous step-down controller IC that operates with a 3V to 5.5V input voltage range and provides a 0.5V to 1.5875V output voltage range. The controller architecture enables upto 12A of load current per phase. Channel 1 has an option to operate with two phases to deliver higher load current, making this device ideal for automotive point-of-load (PoL) and post-regulation applications. The IC achieves ±2% output error over load, line, and temperature ranges. The IC features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response, and a pulse-frequency modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows the use of all ceramic capacitors and minimizes external components. Application includes automotive.
